| Usually system firmware turns off system memory clock |
| signals to unused SO-DIMM slots to reduce EMI and power |

| be disabled. |

| If non-zero, this designates the maximum DDR frequency |

| help |
| On some boards it may be neccessary to hard reset early |
| during resume from S3 if the SLFRCS register indicates that |
| a memory channel is not guaranteed to be in self-refresh. |
| On other boards the check always creates a false positive, |
| effectively making it impossible to resume. |
